# फ़ाइलें

> File upload, metadata और file-content retrieval के लिए C# SDK उपयोग करें।

**Methods**: `client.UploadFile()`, `client.ListFiles()`, `client.RetrieveFile()`, `client.RetrieveFileContent()`।

### उदाहरण

```csharp theme={null}
var client = new Phaseo(apiKey: apiKey);

var uploaded = await client.UploadFile(new Dictionary<string, object>
{
    ["purpose"] = "batch",
    ["file"] = "data:application/json;base64,eyJ0ZXN0Ijp0cnVlfQ=="
});

var file = await client.RetrieveFile("file_123");
var content = await client.RetrieveFileContent("file_123");
```

<Note>
  `ListFiles()` SDK के ज़रिए उपलब्ध है, लेकिन shared gateway key पर `GET /files` अभी `file_list_not_supported_with_shared_gateway_key` लौटाता है
  Uploaded file IDs सहेजें और उन्हें सीधे retrieve करें।
